The polypeptide microarrays assembled are needed to vacuumize sealing, are stored in 4 DEG C of refrigerator, spare.
3. being detected with kit
Checking procedure:
1) temperature of reagent is balanced:All reagents are balanced to room temperature.
2) preparation of washing lotion:Washing lotion purified water will be concentrated or distilled water presses 1:9 dilutions, such as:450mL purified waters or
50mL is added in distilled water and concentrates washing lotion, mixes well.The washing lotion being not used is placed on 2~8 DEG C of preservations, can save 3 months.
3) dilution of sample:Sample to be tested serum dilution is pressed 1:100 dilutions are (such as:2 μ L serum are added to 198 μ L
Serum dilution mixes well).Sample detection needs the 200 μ L of sample after diluting.
4) wetted chip:Take out the biochip incubation reaction device needed for detection.1mL washing lotions are added, infiltrate chip surface 3
Minute.Discard the washing lotion for impregnating chip.
5) it is loaded:In the present embodiment, it is loaded with single side biological incubation reactor, it is to be measured by what is diluted using liquid-transfering gun
Sample is added by liquid feeding venthole (any one in two) in single side biological incubation reactor, each single side biological incubation
Reactor adds 200 μ L, with sealing paste closing liquid feeding venthole (two).
6) sample incubation:The single side biological incubation reactor for adding sample is placed in 150rpm on horizontal shaker, is incubated at room temperature
30 minutes.
7) it cleans:Reaction column is taken out from the reaction cavity of single side biological incubation reactor, discards liquid in reactor,
It rinses inside reaction column top chip surface and reaction cavity repeatedly 3 times (about using 12mL washing lotions every time, rinse 1-2 minutes).
8) enzyme labelled antibody is incubated:Reaction column and reaction cavity are reconfigured, clamping.Throw off sealing paste, each single side life
The 200 μ L of goat-anti people IgM solution of horseradish peroxidase-labeled are added in object incubation reaction device.Again liquid feeding is closed with sealing paste
Venthole.It is placed in 150rpm on shaking table, is incubated at room temperature 30 minutes.
9) it cleans again:Reaction cavity is discarded, chip surface is carefully cleaned with washing lotion 3 times.
10) assay chromogenic substrate solution is added:Each chip surface is separately added into 100 μ L assay chromogenic substrate solutions, keeps colour developing liquid energy uniform
Be laid on chip surface.
11) result judgement:It for every a serum, observes by the naked eye, whether each polypeptide in statistics kit
There is response (i.e. the visible royal purple chrominance signal for being better than negative control point of naked eyes), and is retouched according in above-mentioned " diagnostic method " part
The criterion 1 stated is judged.
To 457 parts of clinical serum being collected into, using the testing result of mentioned reagent box and using traditional goldstandard method-
The testing result of nucleic acid detection method (fluorescent quantificationally PCR detecting kit for using Takara) is compared, as a result such as 1 institute of table
Show.The supplier that 457 parts of above-mentioned clinical serum all has the clinical symptoms of hand-foot-and-mouth disease.
The comparison of the kit of 1 embodiment of table and the fluorescent quantificationally PCR detecting kit of Takara
Accuracy rate=(283+144)/457=93.4%
Sensitivity=283/304=93.1%
Specificity=144/153=94.1%
False positive rate=9/153=5.9%
